3. INTRODUCTION
It is said that freshwater will be the first natural resource to be depleted due to its pollution that is growing increasingly, threatening the ecosystem health and may causing various problems of nutrition and health on a global scale, especially in semiarid regions,such as North Africa and the Middle East. The water scarcity can limit the social and economic development especially on the reagions mentioned above. Thinking about it, it is necessary to create new alternative methods for the sustainable water use as the recycling of rainwater.
4. WHAT IS RECYCLING RAINWATER
Recycling rainwater, also known as rainwater harvesting, collects the rain that fall onto roofs and then stores it in a tank until required for use. When required, the water is then pumped to the point of use or to a secondary tank which distributes the rainwater to the whole establishment, avoiding the demand for mains-water. In the process, a volume of water is kept out of the storm-water management system, to assistance the reducing of flooding risks.
Rainwater harvesting is not a new concept; but, over the last century its use has restricted, with the availability of a clean and inexpensive water source through the mains supply.
Recently, localized flooding started to become a problem once the water demand has begun to exceed supply. Industry experts are now identifying the important role that the harvesting of rainwater, also known as grey water recycling, have to practice in order to improve these two problems.

...groups in order to provide clean and good quality water. In Beijing, the main water distribution system is being complemented by the rainwater collected in houses. When it comes to Africa, some countries such as Guinea-Bissau and Senegal, houses have a rainwater collecting system made of local, organic materials. In Zimbabwe, where the populations mostly has access to water via contaminated open wells, the government is implementing a program to ensure safe drinking water to rural schools through the installation of rooftop rainwater harvesting system.
9. CONCLUSION
Analysing the research and studies for the construction of this report, it can be concluded that recycling rainwater is a sustainable way of water usage and its use have increasingly been assimilated by companies, buildings and people who are interested in smart ways to reuse, recycle and save water.
Storm Water Drainage: This is simply the water from rain, melted snow, etc. draining into
Storm waters are widely used in many different areas, even required in some. They are a vital tool that helps keep streams healthy. Storm water ponds are used to capture, control, and filter all kinds of runoff that could be from anything like parking lots to roof tops. The use of storm water ponds is essential to slow the flow of water down, filter out toxins, and improve the health of streams for aquatic life and for consumption purposes. All of that is in efforts to protect local streams.
Have you ever wondered why little rain can cause drastic floods? Why rainwater doesn't just stay in one place, it goes with the force of gravity? If you have, you’ve thought about a cycle called runoff. Runoff can be negative and positive. It can cause floods, or water your crops.
I also learned of four different sustainable solution to the water supply crises which include; conservation, reservoirs, aqueducts and rainwater harvesting. (Dorsner,
This is because only a small part of the population, particularly in developing countries, have access to water of acceptable quality. It is estimated that in some countries only 20% of the rural population has water of satisfactory quality. Based on these statistics, it is clear the urgent need for awareness about caring for water use. Almost without realizing it, we are seriously jeopardizing this essential resource, not for us but for our children's children and their generations, aware that in other parts o...
There are 80 countries that have been suffering from a lack of clean water, and two billion people lack access to freshwater, especially South Africa (Alois). This area of countries is the driest in the world - Sudan, Ethiopia, Egypt and so on. Like in the book A Long Walk to Water by Linda Sue Park, Nya, who lives in Sudan, has been lacking clean water. She has to find water every day for her family. Luckily, Nya got help from Salva who used to live in Sudan and came back from America to build the water system for her village. However, there are still many people around the world that have been suffering to find clean water for basic use. There are many factors that cause a lack of clean water around the world: geography of countries, deforestation,
You might think of rain as nothing other than rain. Rain is much more important than little raindrops falling out of the sky. In some countries that only get a few inches of rain a year, rain is worshiped like a god. I know from experience that people aren’t big fans of the rain, but for me the rain is very important. Also, the rain is something that you should enjoy and be thankful for, and it is definitely something that you shouldn’t hate. If you’re in a place like California where it doesn’t rain a lot, I instantly feel this small surge of joy or happiness. And when it does rain I feel that we should be thankful for it. I also feel like the rain is sort of the beginning or the start of a lot of things. If there was just this one little farm that supplied a small city of people with meat and vegetables, the farm would probably rely on a tank filled with rain water used to provide the crops with water to grow. If this wasn’t possible, then there wouldn’t be any water for crops, and there wouldn’t be any crops to feed the small city and then there wouldn’t be a lot of healthy people because people would need to rely on processed foods.
The sky is turning a dark gray, clouds rolling in with a loud thunderous sound, and the raindrops began to fall. The rain falls from the sky, rolls off the roof of a building structure, and into a cistern. Collection of rain into either a cistern or holding tank is known as rainwater harvesting. By harvesting the water, it can then be used for irrigation and plumbing. Since purchasing 15 acres of land, I learned of this process simply by word of mouth. Then, one day I see an article on social media about how harvesting rainwater may be illegal. Legalization of this process is now being talked about in our state legislatures. Because rainwater is a beneficial natural resource, it should not be illegal to capture it from your own rooftop.
... the use of basic and effective rainwater harvesting technologies. Coca-Cola has installed these technologies in over 200 locations to assist in recharging aquifers. (Case against Coca-Cola Kerala, n.d.)
Rainwater harvesting provides an independent water supply during regional water restrictions and in developed countries is often used to supplement the main supply. In times of harsh weather such as droughts and floods, it provides a fresh supply of clean water as well as in cases of mitigate flooding occurring...
...ds, which allow us to grow using between 50% and 90% less water than a comparable farm not practicing recirculation. Since we recirculate 100% of irrigation water, our greenhouses don't load the municipal drainage system and our plant nutrients don't end up in lakes and rivers.” If more cities use this method then we will have more water, which can be used to grow more crops to feed the world!
We also added a second water container in our house, just for getting water from the
Developed countries struggle with managing water consumption. Our high demand in agriculture, industry, and domestic use further complicates this issue. With increasing urbanization and extravagant changes in lifestyle, our use and wasting of water will only increase. As of this year, nearly 1.1 billion people live without clean drinking water and 2.6 billion live without adequate water sanitation. The McDonald's down the street, however, will sell you a 1/3 pounder burger for only 150 gallons. Changes in lifestyle can easily reduce this number and help not only save water, but money as well. Currently, with our diminishing water supply, one of the main goals of humanitarian organizations is ensuring that everyone has t...
This paper is about water purification. Water that is safe to drink is called potable water. Our freshwater is definitely not evenly put out throughout the world (www.science.howstuffworks.com). More than half of the world’s water supply is contained in just nine different countries: United States, Colombia, Canada, Brazil, the Democratic Republic of Congo, China, India, Russia, and Indonesia (science.howstuffworks.com). The Middle Eastern countries use the least amount of water per person because there are very few natural and reliable sources of fresh and clean water. Right now more than a billion people (about 17% of the world’s population) don’t have access to clean water (www.science.howstuffworks.com).
People from many developing countries are suffering from the scarcity of clean water, while the rest of the country simply take for granted. Habitants of rural poor communities such as Sub-Saharan Africa, are living in a water stressed environment. Residents of these communities have to walk miles at time just to gather water from streams and ponds, even though the water source may contain water-borne disease that can make them very sick. In the rural places that don’t have access to safe clean water, it is very difficult to prevent the spread of viruses. The consumption of contaminated water can be dangerous for health reasons and several people have passed away from these water-borne diseases. Some of these diseases include Cholera, Typhoid, Dysentery, Giardiasis, and Malaria. These unfortunate diseases are currently the cause of numerous deaths, especially in small children. The availability of clean water can prevent many problems in low income communities. The available resources for clean water are very rare, so these water sources need to pass through a process of water sanitation in order to just be sustainable to drink, “The world’s surface is made up of approximately 80% water, which is an indestructible substance. Of this water approximately 97% is salt water, 2% frozen in glaciers, and only 1% is available for drinking water supply using traditional treatment methods” (Thornton). Therefore, properly treated or disinfected
